We use direct numerical simulation to study electrically-driven convection in an annular thin film. The simulation models a laboratory experiment that consists of a weakly conducting, submicron thick liquid crystal film suspended between two concentric electrodes. The film is driven to convect by imposing a sufficiently large voltage across it. The flow is driven by a surface charge density inversion which is unstable to the imposed electrical force. This mechanism is closely analogous to thedoi:10.1103/physreve.76.026305 pmid:17930140 fatcat:ez5fyocvrrb4xdlkzufgneuega
